I agree with Rachela. You should have a competitive NZ salary plus 25% plus housing, transportation, education, medical, tickets home. For one day in Qatar I'd take a taxi up the Corniche to City Center Mall and have a look around. I know, but it really is a "slice of life" in Qatar. Perhaps lunch at City Center then a taxi to the old souk and a walk around followed by dinner there. You'll get a little of the flavor of Doha that way.
